6.2 Wouldn't shut off, now it won't start

Message Title: Message Text:  http  https  ftp  mail    hr     highlight   LI   Quote  Select Emotion SmileWinkSadEmbarrasmentDisgustedBig GrinMadShockedTongueCoolFrownConfused [q]I have an '83 K-30 with a 6.2 that would not shut off the other night. I pulled the key, wiggled it back and forth and even hit the starter once, but it just kept running. After about a minute it finally shut off, but now the thing won't crank. I can hear the starter relay kick on [U]sometimes[/U] and the glowplugs light up every time I turn the key on. I just bought the truck and it is my first Diesel. Not really sure what is used to shut the engine off (solenoid in fuel line??) and not sure how it would be related to the engine not cranking. My first guess was the ignition switch, I pulled it out and checked the contacts, they seem fine. Any suggestions would be appreciated, my email is jzz1r9@aol.com[/q]
